There are several ways to avoid getting unsightly pit stains on your shirts: Allow your anti-perspirant to dry completely, wear an undershirt to protect your dress shirt, avoid wearing the same shirt more than twice between washings. But if you end up with those embarrassing yellow stains, pre-treating with Deo-Go before you do your laundry will generally lift the stains right out and restore your shirt’s original appearance. Just think: Free of the fear of raising your arm and exposing your grotesque pit stains to the world, you’ll never have to duck a high-five again!
